Abstract:
:Seeds of rape (Brassica napus L.) were germinated at various NaCl concentrations up to 200 mM. Germinating levels, seedling growth, triacylglycerol mobilization and lipase activity were investigated. High salt concentrations resulted in retardation of seed germination. Seedling growth as measured by radicle length was severely reduced by NaCl doses higher than 50 mM. Moreover, the mobilization of storage oil in control rapeseed seedlings, started about 24 h after imbibition. As for germination and growth, elevated salt concentrations are found to delay triacylglycerol degradation. Experiments using triolein as substrate indicated clearly that lipase activity was inhibited by salt treatment.
